ELEVATOR-BUCKET.

SPECIFICATION forming part of Letters Patent No. 413,061, dated October15, 1889..

Serial No. 303,385. (No model.)

To all whom it may concern:

Be it known that I, LYMAN D. HOWARD, a citizen of the United States,residing in the city and county of Philadelphia, State of Pen nsylvania,have invented a new and useful Improvement in Elevator-Buckets, whichimprovement is fully set forth in the following specification andaccompanying drawings.

My invention relates to improvements in elevator-buckets; and itconsists in a bucket with a pivoted door haviir spring-catches securedthereto, the noses of? she catches being adapted to engage the bacy; ofthe bucket and the catch .being secured in keepers having springsbearing on said catch.

It further consists in the ombination of parts herein described andclaimed.

Figure 1 represents a side elevation of an elevatorbucket embodying myinvention. Fig. 2 represents a rear view of the bucket shown in Fig. 1.Fig. 3 represents a top or plan view thereof.

Similar letters of reference indicate corre spending parts in the threefigures.

Referring to the drawings, A designates an elevator-bucket, and B thechains to which the same is hung.

O designates the door of the bucket, the same having its axis at or nearthe top of the 0 bucket, as at C. To the lower end of the door, at thesides thereof, are secured catches D, whose noses E engage with the backof the bucket, the catches being pivoted to the door or made elastic,whereby they are capable of lateral motions.

Secured to the frame of the elevator in the path of the noses of thecatches is a releasing device for said catches, the same consisting of abeam F, whose ends are sloping or rounding upward and so disposed thatthey are engaged by the inner faces of the noses E. It will be seen thatwhen the catches are in their normal positions the door of the bucket isheld closed. As the bucket rises the noses of the catches ride on theends of the beam F, thus gradually forcing out the catches from theirengagement with the back of the bucket, which being accomplished thedoor is no longer controlled by said catches, and

the pressure of the contents of the bucket is case located in thekeepers or guides H 6o through which the catches pass at the sides ofthe bucket.

The bottom of the bucket is sloping at an angle to line of motionsufficient to allow the load to be released by gravity.

The rollers G G" of the elevator are arranged to close the door, theroller G engaging said door and the roller G being placed in contactwith chains at each side, thus preventing the bucket from. swingingbackward when the door is brought in contact with the roller G, therebyreliably insuring the closing of the door.

Having thus described my invention, what I claim as new, and-desire tosecure by Letters Patent, is

1. An elevator -bucket having a pivoted door, catches connected withsaid door and having noses adapted to engage the back of the bucket whenthe door is closed, keepers secured to the sides of the bucket and inwhich the catches play, and springs in said keepers bearing against saidcatches, said parts being combined substantially as and for the purposeset forth.

2. An elevator -bu cket having a pivoted door, catches secured to saiddoor, keepers in which said catches play, and springs bearing againstsaid catches, the said catches having noses adapted to engage the backof said bucket, and a tripping device consisting of a beam with sidesrounding upward, the outer ends of the noses being adapted to engagesaid beam, said parts being combined substantially as described.
